Resona: Resonance Breathing

Train for better HRV with breathing that adapts to your physiology. Most breathing exercises use the same pace for everyone. Resona does something different. Using live beat-to-beat heart data from a compatible Bluetooth heart rate monitor, Resona explores how your body responds to different breathing rhythms. It learns which rhythm produces your strongest and most stable response, then uses that insight to personalize future sessions. The goal is simple: to help you build a breathing practice that can support higher HRV, a calmer response to stress and better recovery. PERSONALIZED TO YOUR PHYSIOLOGY Your ideal breathing rhythm is personal. During measured sessions, Resona gradually tests and refines the pace that works best for your body. As your rhythm becomes clearer, your sessions become more individually tailored. MEASURE YOUR RESPONSE Resona turns breathing practice into something you can follow over time. See how your body responded during each measured session and explore changes in your: • Personal breathing rhythm • Resona Score • Time to calm • Resonance stability • Perceived effect • Practice consistency Once Resona has learned your rhythm, you can also continue guided sessions without wearing your heart rate monitor.
